Replacing overvoltage protection

Replace the DC overvoltage protection
F NOTE: If a fault appears on the status display of the overvoltage pro-
tection mode, the overvoltage protection should be replaced.
↻ NOTE: A check has been performed to ensure there is no AC/DC
voltage present.
1. Opening the device Opening the device [See section 6.2}[15].
2. Unlock faulty modules via the locking latch.
3. Remove faulty modules individually from the DC base and replace with a mod-
ule of the same type.
. NOTE: The coding at the base plug-in position must match the cod-
ing on the module.
4. Insert the DC overvoltage protection modules into the DC base one after an-
other.
5. Secure new modules using the locking latch.
6. Ensure that all protective elements are properly secured.
ð Proceed with the installation of the device.

Disconnecting connections

7.6.1

AC connection

↻ It has been ensured that there is no AC/DC voltage present.
↻ Housing cover removed and set to one side.
1. Detach cables (L1/L2/L3) from the AC connection terminal [ W_17].
2. Detach the PE line from the earthing bolt [ W_17].
3. Loosen the cable fitting and pull the cables out through the cable fitting [ W_46].
. NOTE: If the AC cable does not fit through the cable fitting due to the size of the cable lug,
then the AC cable must be severed at the cable lug.
4. Place protective caps on the ends of the AC cables.
7.6.2

DC connection

↻ A check has been performed to ensure there is no DC voltage present.
↻ Housing cover removed and set to one side.
1. Detach the line ends from the PV generator at the DC+ and DC- busbar [ W_17].
2. Place the fastening elements back in the fittings bag.
3. Loosen the cable fitting and pull the DC cable through the cable fitting [ W_46].
